How to close the data subscription about mida

[Vasile-Peste]

Hi, everytime you create a listener with the on method, the subscription will return a unique ID that can be used to unsubscribe from the event.

So taking your example, you basically do as follows

const uuid = marketWatcher.on("period-close", (event) => { ... });

marketWatcher.removeEventListener(uuid);

Closing the data stream is handled internally when Mida is certain that there are 0 active listeners.
For reference https://www.mida.org/documentation/utilities/events.html#removeeventlistener
I will try to improve this part of documentation, thank you
